Heap profiling in GHC broken?

[Markus.Schnell at infineon.com]

Hi.
When I tried to profile my program in search for space leaks,
it core dumped on me (actually on Win2000/Cygwin). I'm using ghc 6.0.1. 
Does anybody know what could be the problem?

(To be more precise: any +RTS -h_ options make problems, +RTS -p works fine.
 I get a message meaning the equivalent of "statement in '0x0058db43' points

 to memory in '0xfffffffc'. Could not read.")

Cheers,
Markus
